Limit value:The maximum or minimum limit value that should not be exceeded at inspection and adjustment.
Units INFOID:0000000004053031
• The UNITS given in this manual are primarily expressed as the SI UNIT (International System of Unit), and
alternatively expressed in the metric system and in the yard/pound system.
Also with regard to tightening torque of bolts and nuts, there are descriptions both about range and about the
standard tightening torque.

Contents INFOID:0000000004053032
• A QUICK REFERENCE INDEX, a black tab (e.g. ) is provided on the first page. You can quickly find the
first page of each section by matching it to the section's black tab.
• THE CONTENTS are listed on the first page of each section.
• THE TITLE is indicated on the upper portion of each page and shows the part or system.
• THE PAGE NUMBER of each section consists of two or three letters which designate the particular section
and a number (e.g. “BR-5”).
• THE SMALL ILLUSTRATIONS show the important steps such as inspection, use of special tools, knacks of
work and hidden or tricky steps which are not shown in the previous large illustrations.
Assembly, inspection and adjustment procedures for the complicated units such as the automatic transaxle
or transmission, etc. are presented in a step-by-step format where necessary.
Component INFOID:0000000004053033
• THE LARGE ILLUSTRATIONS are exploded views (see the following) and contain tightening torques, lubri-
cation points, section number of the PARTS CATALOG (e.g. SEC. 440) and other information necessary to
perform repairs.
The illustrations should be used in reference to service matters only. When ordering parts, refer to the
appropriate PARTS CATALOG.
Components shown in an illustration may be identified by a circled number. When this style of illustration is
used, the text description of the components will follow the illustration.

3. Refer to Component Parts and Harness Connector Location for the Systems described in each
section for identification/location of components and harness connectors.
4. Refer to the Circuit Diagram for quick pinpoint check.
If you need to check circuit continuity between harness connectors in more detail, such as when a
sub-harness is used, refer to Wiring Diagram in each individual section and Harness Layout in PG
section for identification of harness connectors.
5. When checking circuit continuity, ignition switch should be OFF.
6. Before checking voltage at connectors, check battery voltage.
7. After accomplishing the Diagnostic Procedures and Electrical Components Inspection, make sure
that all harness connectors are reconnected as they were.
HOW TO FOLLOW TEST GROUPS IN TROUBLE DIAGNOSES
1. Work and diagnostic procedure
Start to diagnose a problem using procedures indicated in enclosed test groups.
2. Questions and required results
Questions and required results are indicated in bold type in test group.
The meaning of are as follows:
3. Symbol used in illustration
Symbols included in illustrations refer to measurements or procedures. Before diagnosing a problem,
familiarize yourself with each symbol. Refer to "Connector Symbols" in GI Section and "KEY TO SYM-
BOLS SIGNIFYING MEASUREMENTS OR PROCEDURES" below.
4. Action items
Next action for each test group is indicated based on result of each question. Test group number is shown
in the left upper portion of each test group.
HARNESS WIRE COLOR AND CONNECTOR NUMBER INDICATION
There are two types of harness wire color and connector number indication.
TYPE 1: Harness Wire Color and Connector Number are Shown in Illustration
SAIA0256E
a. Battery voltage → 11 - 14V or approximately 12V
b. Voltage : Approximately 0V → Less than 1V

• Connector numbers in a single circle M33 indicate harness con-
nectors.
Component Indication
Connector numbers in a double circle F211 indicate component connectors.
Switch Positions
Switches are shown in wiring diagrams as if the vehicle is in the “normal” condition.
A vehicle is in the “normal” condition when:
• ignition switch is “OFF”,
• doors, hood and trunk lid/back door are closed,
• pedals are not depressed, and
• parking brake is released.
Detectable Lines and Non-Detectable Lines
In some wiring diagrams, two kinds of lines, representing wires, with different weight are used.
AGI070
SGI860

GI-14
• A line with regular weight (wider line) represents a “detectable line
for DTC (Diagnostic Trouble Code)”. A “detectable line for DTC” is
a circuit in which ECM can detect its malfunctions with the on
board diagnostic system.
• A line with less weight (thinner line) represents a “non-detectable
line for DTC”. A “non-detectable line for DTC” is a circuit in which
ECM cannot detect its malfunctions with the on board diagnostic
system.
Multiple Switch
The continuity of multiple switch is described in two ways as shown below.
• The switch chart is used in schematic diagrams.
• The switch diagram is used in wiring diagrams.

HOW TO FOLLOW TROUBLE DIAGNOSES
NOTICE:
Trouble diagnoses indicate work procedures required to diagnose problems effectively. Observe the following
instructions before diagnosing.
• Before performing trouble diagnoses, read the “Work Flow” in each section.
• After repairs, re-check that the problem has been completely eliminated.
• Refer to Component Parts and Harness Connector Location for the Systems described in each section for
identification/location of components and harness connectors.
• When checking circuit continuity, ignition switch should be OFF.
• Refer to the Circuit Diagram for quick pinpoint check.
If you need to check circuit continuity between harness connectors in more detail, such as when a sub-har-
ness is used, refer to Wiring Diagram in each individual section and Harness Layout in PG section for identi-
fication of harness connectors.
• Before checking voltage at connectors, check battery voltage.
• After accomplishing the Diagnosis Procedures and Electrical Components Inspection, make sure that all
harness connectors are reconnected as they were.
How to Follow Test Groups in Trouble Diagnosis INFOID:0000000004053038
1. Test group number and test group title
• Test group number and test group title are shown in the upper portion of each test group.
2. Work and diagnosis procedure
• Start to diagnose a problem using procedures indicated in enclosed test groups.
3. Questions and results
• Questions and required results are indicated in test group.
4. Action
• Next action for each test group is indicated based on result of each question.
